  Abstract

In this study, viscose fiber (VF), as the raw material, was utilized to prepare the activated carbon fiber. The porous structure of the viscose-base activated carbon fiber (VACF) was obtained via a hybrid activation combining physical and chemical methods. The physicochemical properties of VACF were carried out and analyzed. The results showed that the specific surface area and pore volume of the samples increased. The specific surface area of VACF can reach up to 1846.65 m2/g. The effectiveness of VACF prepared in the adsorption of Cd(II) and As(V) has been studied as a function of pH, time and initial concentration. All adsorption processes fit the pseudo-second-order model and Freundlich isotherm equation. The maximum adsorption capacity of VACF for Cd2+and AsO4 3- is 483.12 and 400.36 mg/g. In addition, the sample still has high removal property after repeated cyclic adsorption. This study provides a new disposal solution for viscos fibers and in further the textile fibers as well a feasible strategy for heavy metal pollution treatment.
